What are the dangers of cul-de-sac development? (Photo: TheMuuj via Flickr.)

For me the highlight presentation on opening day…was about the safety effects of different street network types.

The study was based on looking at all cities in California with
population of 40,000 or greater. The surprising finding was that cities
built before 1950 are safer (in terms of both serious injuries and
fatalities for all classes of users: auto drivers/passengers, cyclists
and pedestrians) than cities built after 1950.

The differences appears to be in the type of street network. Compact
street grids seem to be safer, compared to the arterial-collector-local
street ‘tree’ style of street network popular in post-war development.

No link to the study itself yet, but we’re interested in hearing more.

Word On The Street

“The fact we cannot say definitively that ticketing cyclists for not making full and complete stops necessarily decreases injuries or otherwise reduces collisions gets to the very heart of the issue: Sanford's impending crackdown is not data-driven...
And all the while, this crackdown will better enable motorists near and far to continue, without consequences, to commit the five traffic violations that the data clearly shows us are causing the greatest harm to the most road users.
Bias, bias, bias.”
